First check the heater core, as if it is restricted, you will get no heat. Check the hose going in and the hose coming out of the core, located on the firewall behind the engine. If one hose is hot and the other is cool - then you have a restriction issue.

If both hoses are very hot, you could have a temperature control issue inside the vehicle.
